Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to a theft protection device for closing and restoring fluid flow, and in particular to a theft protection device for motor vehicles with internal combustion engines, diesel engines.

b. Prior Art In order to protect motor vehicles from theft, which is becoming more and more frequent these days, a large number of such theft safety devices are now known.

The best known and economical theft protection devices include the so-called "theft protection steering lock" and others that operate on the same principle. These fix all or part of the rotation of the steering wheel. The former is not very efficient, whereas the latter is usually a chain that wraps around the steering wheel and seat of a motor vehicle, or a rod that secures the steering wheel and control pedals, such as the brake pedal. However, these are rather inconvenient to install and remove.

There is therefore a rather expensive electronic device which acts on the electrical equipment of the motor vehicle when it is not switched off using a particular key within a predetermined time period.

Typically, these devices are set to activate the motor vehicle's acoustic horn so that the sound attracts attention and deters thieves from approaching.

C1 The problem that the invention seeks to solve The problem with these devices is that sometimes they will malfunction for reasons unrelated to theft, e.g. because some part of the circuit malfunctions; The problem is that the user often ends up turning off the switch because it often occurs, sometimes even during the night.

Along with this device, other similar electronic devices are currently installed, and switches are opened and closed by ultrasound devices.

Since this device acts on the ignition circuit of the engine of the motor vehicle, it is extremely quiet.

However, even in this case, it sometimes occurs that the electronic device operates due to the user's own carelessness while the ultrasound device is in operation. For example, when driving the motor vehicle with the windows open.

Therefore, in this latter case, there is a problem in that the theft safety device is dangerous for the safety of the driver of the motor vehicle, etc., who may suddenly stop the vehicle, for example, when overtaking the vehicle.

The present invention has been made in view of the above problems, and its purpose is to provide a theft protection device for a motor vehicle that is truly reliable, efficient, and particularly useful against theft of a motor vehicle. It is about providing.

d. Means for Solving the Problems To achieve the above object, the present invention provides a theft protection device for a motor vehicle having an internal combustion engine, the device being connected to a fuel supply pipe to the engine of the motor vehicle. A device body having a transversely formed bent through hole therein as a fuel supply passage for closing and restoring the flow of fuel fluid by disposing it between the passages, and having at least and a closing member that is freely rotatable and has a through hole bored transversely therein, and each of the closing members has a position of the through hole independently of each other, and each of the closing members has a position of the through hole independently of the other, and is characterized in that it communicates with the through hole in the body only when it is in a predetermined series of positions relative to the body.

One advantage of the invention is its simple construction and construction, making it extremely economical and efficient at the same time.

In fact, as a theft protection device for a motor vehicle, the main body of the device is arranged between the fuel supply pipes to the engine and has an internally curved through passage, and the main body has a predetermined one installed in the main body. At least one closure element adapted to restore the passageway in said body is sufficient during manufacture only when in position . That is, electrical continuity of the device is obtained only by a combination of predetermined positions of each closure member relative to the body.

e. Examples Hereinafter, preferred embodiments of the present invention will be described in detail by way of example with reference to the drawings.

A cross-sectional view of one embodiment of the present invention is shown in FIG. As shown in the figure, the theft protection device in this embodiment is disposed between a conduit 7 for supplying fuel to an internal combustion engine (not shown) of a motor vehicle, and is arranged between a device body 1 and an internal combustion engine inside the body 1. two closing members 3 each held by a retaining member 6.6 at
．． Consists of 3.

A through hole 2 is provided in the main body 1 so as to pass through a through hole 4 formed in a part of the closing member 3, and both ends are attached to the cut end of the fuel supply pipe 7. has a connecting element (not shown).

The closing member 3 is rotatable and can have different shapes, and each through hole 4 is drilled only in a part of the closing member 3 to restore electrical continuity to the through hole 2 provided in the main body l. In order to do this, it communicates with the through hole 2.

The theft protection device is thus manufactured as a single position combination device, and only when all the through holes 4 in the closure member 3 communicate with said through holes 2 in the body 1 can fuel fluid flow through the device. A flow is formed.

In order to avoid unauthorized manipulation or tampering, the passage of the hole 2 drilled in the body 1 is curved. For this reason, it is impossible to find the correct positional combination of the members by inserting a rod-shaped body into the hole 1 and moving the closing member 3 so that the rod-shaped body communicates with the hole 2.

In addition, in order to avoid unauthorized access, various external members are
It is made of a material hard enough that it cannot be drilled with a regular drill. Furthermore, the protective element 6 is fitted to the removable body 1 only at the factory and only after the device has been removed from the motor vehicle.

In the embodiment of FIG. 1, the body 1 is cylindrical and has an H-shaped cross-section along its axis, in which a disk-shaped closing member 3.3 is mounted.

In this case, one of the connecting holes in the body 1 with the fuel supply line 7 is perpendicular to the axis of the body 1, and the other connecting hole is parallel. The holes 4 of the two closure members 3.3 are mutually coaxial and parallel to the axis of the body 1. In order to avoid tampering, the parts of the through holes 2 and 4 are connected by a part forming an acute angle or a part forming a mostly right angle.

In another embodiment shown in FIGS. 2 and 3, the body 1 is a parallelepiped with three holes drilled parallel to each other and arranged - on the sides - in a straight line. , in which a respective cylindrical closure member 3.3 is mounted. The through-hole 4.4 is drilled diametrically with respect to the associated closure member 3, 3, the hole 2 is arranged in the longitudinal direction of the body 1 and the cross-section of its end section forms a Z-shaped passage. Form.

As shown in FIGS. 1 and 2, this g1 is also an embodiment applied to a diesel engine, and a tooling gasket 8 is provided to prevent leakage since the fuel fluid becomes under high pressure.

In both embodiments, the closure member 3.3 is thus rotatable about its axis. For this purpose each closing member 3.3
has a shaft 9.9 projecting from the respective holding member 6,6. A selector knob 10.10 with index marks for indicating the different possible positions of the respective closure member 3.3 is mounted on each said shaft 9.

(See Figure 2).

Each shaft 9 (see first part) may also be the output shaft of an electronic drive means, such as a stepper motor 5.5 of known type. In this case, the controllers for the cough motors 5, 5 can be relocated to the interior of the motor vehicle, so theft protection is possible.
It can be seen that it becomes more convenient and efficient as a vi location. Even in this case, if the selector knob 10 is also provided, it can be used even if each motor 5 breaks down.

It is also possible to provide each closure member such that it is mechanically stable in each selected position. This obviously serves the purpose of ensuring the stability of each closure member 3 during use under any conditions of the motor vehicle.

If the device of this embodiment is installed in a motor vehicle having a carburetor gasoline engine, the device should be designed to Preferably, a switch is provided to open the electrical supply circuit of the engine when the position combination is incorrect.

As a further embodiment (not shown), it is conceivable that the main body 1 of the device is integrally formed with the main body of the fuel pump of the motor vehicle in order to be efficient and to prevent unauthorized access. In certain types of motor vehicles,
The device described above can also be mounted on the fuel tank, in which case it is conceivable that the main body l of the device is likewise molded in one piece with the fuel tank.

Furthermore, the closing member 3 within the main body 1 can be constructed with a deformed cylindrical shape. In this case, the cylindrical closure member may be rotatably incorporated in a single member so as to double the combination.

The invention thus conceived is susceptible to many modifications and variations that fall within the same inventive concept.

Furthermore, structural details can be replaced by technically equivalent means. For example, instead of being pivotable, the closure member 3 could be slidable, or it could also be arranged in a completely different manner from that shown in the accompanying drawings.

f. Effects of the Invention As is clear from the above description, the present invention has a simple configuration and structure, is reliable and efficient, is particularly useful in use, and is extremely economical in manufacturing. be.

Another advantage of the present invention is that even when a rod-like body is inserted into a hole in the main body, the hole has a curved passage, and in order to prevent the rod-like body from reaching the closing member, a predetermined combination of the same members is provided. Can't find location. In this way Book'A 71
1, the structure is such that unauthorized manipulation or manipulation is impossible.

What is particularly important is that the device allows the flow path to be opened and closed only by the user, and that it cannot be opened or closed by certain ambient conditions or the like. For this reason, while using a motor vehicle,
There is no danger even if the device is suddenly set up. In this regard, it is noteworthy that a switch can be arranged in the electrical supply circuit of the carburetor engine, which is operated directly or indirectly by means of one or more closing members.

This device is particularly convenient because its closing member can be operated by a snapping motor, so that the control for opening and closing the device can be relocated into the passenger compartment of the motor vehicle.

Due to its strong structure, it can be installed in motor vehicles that are subject to harsh operating conditions, such as trunks and bulldozers.
